Description

Beim Bau von Trockengleichrichtern besteht die Schwierigkeit, die Gleichrichter mit einem Überzug zu versehen, der mehrere Eigenschaften in sich vereinigen soll. Er soll elektrisch isolierend sein, er soll wärmebeständig sein, d. h., er soll bei Betriebstemperatur nicht brüchig oder weich werden, und soll die Wärmeausdehnung des Gleichrichters mitmachen, ohne zu reißen und eine gute Wärmeleitfähigkeit haben, endlich soll er noch wasserundurchlässig und widerstandsfähig gegen Dämpfe von Säuren und Laugen sein und darf keine Flüssigkeiten aufsaugen. Die bisher verwendeten Lacke erwiesen sich stets in der einen oder anderen Richtung als ungeeignet, so daß es äußerst umständlich war, einen Gleichrichter zu bauen, der allen Anforderungen gerecht wurde. Es sind auch bereits Trockengleichrichter beschrieben worden, die von Wachsen, Harzen oder Kunststoffen umgeben oder vergossen waren. Nun war es bislang sehr schwer, derartige Gleichrichter einer künstlichen Kühlung auszusetzen, weil das Kühlmittel durch die Überzugsmasse verhältnismäßig weit von den die Wärme erzeugenden Teilen der Trockengleichrichter entfernt gehalten wurde.The difficulty in building dry rectifiers is that To provide rectifiers with a coating that combines several properties target. It should be electrically insulating, it should be heat-resistant, d. h., he should not become brittle or soft at operating temperature, and should allow thermal expansion the rectifier join in without cracking and have good thermal conductivity, Finally, it should still be impermeable to water and resistant to vapors from acids and alkalis and must not suck up any liquids. The paints used so far always proved to be unsuitable in one direction or the other, so that it It was extremely cumbersome to build a rectifier that met all requirements became. Dry rectifiers have also already been described, which are made of waxes, Resins or plastics were surrounded or encapsulated. Now it has been very difficult so far to expose such rectifiers to artificial cooling because the coolant relatively far from the heat-generating parts due to the coating compound the dry rectifier was kept away.

Die Erfindung bezieht sich nun auf einen Trockengleichrichter, insbesondere einen Selengleichrichter, der aus mehreren Gleichrichterelementen, vorzugsweise in Säulenform, aufgebaut und bei dem der ganze zwischen den Bauelementen befindliche Raum mit Gießharz ausgefüllt ist. Erfindungsgemäß ist der mit Gießharz ausgegossene Raum von einem oder mehreren zwischen den Gleichrichterplatten liegenden Kanälen zum Durchleiten eines Kühlmittels derart durchsetzt, daß alle Bauelemente des Gleichrichters noch mit einer dünnen Schicht Gießharz bedeckt sind.The invention now relates to a dry-type rectifier, in particular a selenium rectifier, which consists of several rectifier elements, preferably in the form of a column, built up and in which the whole is located between the components Space is filled with resin. According to the invention is the one poured with resin Space from one or more ducts lying between the rectifier plates for passing a coolant through so that all components of the rectifier are still covered with a thin layer of casting resin.

Der ganze Gleichrichter wird mit einem Kühlmittel, wie Wasser oder Öl, betrieben. Bei Kühlung mit Luft kann die sich in den Kanälen ausbildende Kaminwirkung durch einen künstlichen Luftstrom verstärkt werden.The whole rectifier comes with a coolant, such as water or Oil operated. When cooling with air, the chimney effect that forms in the ducts can occur be amplified by an artificial air flow.

Man braucht also bei der Wahl der Betriebsbedingungen, insbesondere der Kühlmittel, keine Rücksicht mehr auf die vielfältigen Eigenheiten des Gleichrichters zu nehmen.So you need to choose the operating conditions, in particular the coolant, no longer considering the various peculiarities of the rectifier gain weight.

Als Gießharz eignet sich besonders ein Material, dessen Füllstoff eine größere Wärmeleitfähigkeit als das Gießharz selbst aufweist, also vorzüglich ein Material mit Holzmehl oder Quarzmehl als Füllstoff.A material, its filler, is particularly suitable as the casting resin has a greater thermal conductivity than the casting resin itself, so excellent a material with wood flour or quartz flour as a filler.

Zur Herstellung eines Gleichrichters, bei dem das Gießharz von Kanälen durchsetzt ist, hat sich ein Verfahren bewährt, nach dem zwischen die Bauelemente beim Vergießen Verdrängungsstücke gesetzt werden, die nach dem Guß wieder entfernt werden und die Kanäle zurücklassen. Die Figuren zeigen in zum Teil schematischer Darstellung Ausführungsformen eines Trockengleichrichters gemäß der Lehre der Erfindung.For the production of a rectifier in which the cast resin of channels is penetrated, a method has proven itself, according to which between the components when potting, displacement pieces are set, which are removed again after casting and leave the canals behind. The figures show in part schematically Representation of embodiments of a dry rectifier according to the teaching of the invention.

In Fig. I trägt der Bolzen I die Trockengleichrichterelemente 2 sowie die Distanzstücke 3. Alle Bauelemente sind von einer Gießharzschicht 4 umgeben, die außerdem um den ganzen Gleichrichter einen geschlossenen Mantel bilden.In Fig. I, the bolt I carries the dry rectifier elements 2 as well the spacers 3. All components are surrounded by a cast resin layer 4, which also form a closed jacket around the entire rectifier.

Der Gleichrichter nach Fig. 2 ist in einem Gehäuse 5 untergebracht, so daß der Bolzen I nach Fig. I entfallen kann. Im übrigen ist der Aufbau genau der gleiche wie nach Fig. I.The rectifier according to Fig. 2 is housed in a housing 5, so that the bolt I according to FIG. I can be omitted. Otherwise the structure is precise the same as in Fig. I.
